I know that it's frustrating, but you're getting a good education on how and why a 1911 is a good basic weapon! First, determine if it's the ammo or the gun. Take the barrel out of the gun and drop EACH round you will shoot into the barrel. Each round should slide easily and fully into the chamber (the rim flush, or a hair below, the hood of the barrel). You can visually see if the barrel is clean or collecting lead. Not "Brain-Surgeon" work! Then start experimenting with magazines. You can buy kits that replace the magazine springs, and followers, at Brownell's, Wilson's, etc. Once you understand the 1911, you can turn most "lemons" into good reliable and accurate handguns. Be patient and good luck. One other tip. I've had my best luck with STANDARD, 16 lb., recoil springs and NO shok-buff's!
